ytop displays negative temperature value

Problem

On iMac (but not on older MacBooks) sysinfo provides - and ytop displays - wrong temperature.
Note: I cloned sysinfo, and added some sensors (PECI CPU, and a couple more of such) to see what sensors report correctly on both Mac platforms). I found that all of those sensors give correct values on MacBook, but some fail on iMac Pro.

Proposed Workaround

While we're discussing with @GuillaumeGomez the possibility of fixing sysinfo library - it would be nice if ytop could validate (sanity-check) inputs it receives from it. In this particular case, I'd love if ytop would check the received CPU temperature either against zero, or against CPU Proximity, and if it is lower (i.e., lower than zero, or lower than CPU Proximity) - ignore/drop that value and don't display it.

Could you do that, please?
